The article says there are five main castes with thousands of sub-castes. To be precise the Dalits are not considered a caste. They are outside of the Caste system and lower than the lowest of the low, the Sudras. In practice however today's Indian has seven Caste, at least normalized in Western countries such as Europe and the US. In this revised Caste system, the Whites are at the top, higher than the Brahmins and Blacks are at the bottom, lower than the Dalits. I have witnessed firsthand how a Black colleague of mine was treated by his Indian counterparts in the IT industry. It is pretty disgusting to say the least.
